For example, getting all rows where id is 5: ``` cursor.execute("SELECT * FROM t1 WHERE id = %s", (5,)) ``` If you want each single statement in the script to be related to its corresponding result set, you should enable the `map_results` switch - see workflow example below. If the given script uses `DELIMITER` statements (which are not recognized by MySQL Server), the connector will parse such statements to remove them from the script and substitute delimiters as needed. This pre-processing may cause a performance hit when using long scripts. Note that when enabling `map_results`, the script is expected to use `DELIMITER` statements in order to split the script into multiple query strings. The following characters are currently not supported by the connector in `DELIMITER` statements: `"`, `'`, #`, `/*` and `*/`. If warnings were generated, and `connection.get_warnings` is `True`, then `self.warnings` will be a list containing these warnings. Args: operation: Operation to be executed - it can be a single or a multi statement. params: The parameters found in the tuple or dictionary params are bound to the variables in the operation. Specify variables using `%s` or `%(name)s` parameter style (that is, using format or pyformat style). map_results: It is `False` by default. If `True`, it allows you to know what statement caused what result set - see workflow example below. Only relevant when working with multi statements. Returns: `None`. Example (basic usage): The following example runs many single statements in a single go and loads the corresponding result sets sequentially: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation) result_set = await cur.fetchall() # do something with result set ... while (await cur.nextset()): result_set = await cur.fetchall() # do something with result set ... ``` In case the operation is a single statement, you may skip the looping section as no more result sets are to be expected. Example (statement-result mapping): The following example runs many single statements in a single go and loads the corresponding result sets sequentially. Additionally, each result set gets related to the statement that caused it: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) # statement 1 is `SET @a=1, @b='2024-02-01'`, # result set from statement 1 is `[]` - aka, an empty set. result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... # 1st call to `nextset()` will laod the result set from statement 2, # statement 2 is `SELECT @a, LENGTH('hello'), @b`, # result set from statement 2 is `[(1, 5, '2024-02-01')]`. # # 2nd call to `nextset()` will laod the result set from statement 3, # statement 3 is `SELECT @@version`, # result set from statement 3 is `[('9.0.0-labs-mrs-8',)]`. # # 3rd call to `nextset()` will return `None` as there are no more sets, # leading to the end of the consumption process of result sets. while (await cur.nextset()): result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... ``` In case the mapping is disabled (`map_results=False`), all result sets get related to the same statement, which is the one provided when calling `execute()`. In other words, the property `statement` will not change as result sets are consumed, which contrasts with the case in which the mapping is enabled. Note that we offer a new fetch-related API command which can be leveraged as a shortcut for consuming result sets - it is equivalent to the previous workflow. ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) async for statement, result_set in cur.fetchsets(): # do something with result set ``` Nryrprrrs rfrzMySQLCursorAbstract.executerrhc KdS)aExecutes the given operation (it can be a multi statement or a MySQL script) substituting any markers with the given parameters. **NOTE: `executemulti()` is deprecated and will be removed in a future release.

This capability reduces performance. **Unexpected behavior might happen if your script includes the following symbols as delimiters `"`, `'`, `#`, `/*` and `*/`. The use of these should be avoided for now**. Refer to the documentation of `execute()` to see the multi statement execution workflow.

This method will prepare the given operation and execute with each tuple found the list seq_params. If the cursor instance already had a prepared statement, it is first closed. executemany() simply calls execute(). Nry)rprrs rf executemanyzMySQLCursorAbstract.executemanyrrhrc KdS)zReturn next row of a query result set. Raises: InterfaceError: If there is no result to fetch. Returns: tuple or None: A row from query result set. Nryrs rfrzMySQLCursorAbstract.fetchonerrh List[RowType]c KdS)zReturn all rows of a query result set. Raises: InterfaceError: If there is no result to fetch. Returns: list: A list of tuples with all rows of a query result set. Nryrs rffetchallzMySQLCursorAbstract.fetchallrrhrFsizeList[Sequence[Any]]c KdS)a<Return the next set of rows of a query result set. When no more rows are available, it returns an empty list. The number of rows returned can be specified using the size argument, which defaults to one. Returns: list: The next set of rows of a query result set.

Returns: A 2-tuple; the first element is the statement that caused the result set, and the second is the result set itself. Example: Consider the following example where multiple statements are executed in one go: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... while (await cur.nextset()): result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... ``` In this case, as an alternative to loading the result sets with `nextset()` in combination with a `while` loop, you can use `fetchsets()` which is equivalent to the previous approach: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) async for statement, result_set in cur.fetchsets(): # do something with result set ``` N)rrLrr2nextset)rpstatement_cached result_sets rf fetchsetszMySQLCursorAbstract.fetchsetssrh % .#~  #}}......JJ   JJJ #4 JDNN:J     LLNN""""""  #'==??222222 !     #'"8N>N     LLNN""""""     s/ >>1B BBrc KdS)aKMakes the cursor skip to the next available set, discarding any remaining rows from the current set. This method should be used as part of the multi statement execution workflow - see example below. Returns: It returns `None` if there are no more sets. Otherwise, it returns `True` and subsequent calls to the `fetch*()` methods will return rows from the next result set. Example: The following example runs many single statements in a single go and loads the corresponding result sets sequentially: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation) result_set = await cur.fetchall() # do something with result set ... while (await cur.nextset()): result_set = await cur.fetchall() # do something with result set ... ``` In case the operation is a single statement, you may skip the looping section as no more result sets are to be expected.
